On his way to the altar, famed adventurer Hugh "Bulldog" Drummond is sidelined by a bank robbery committed by master thief Henri Armides (Eduardo Ciannelli). The cash is stashed in a radio and shipped to France. Both Bulldog and his bride-to-be give chase, culminating in a harrowing dash to save themselves from being blown to bits in a devastating explosion. John Howard and Heather Angel co-star in this next-to-last entry in the popular H.C. McNeile detective series. The film also features returning players E.E. Clive as Bulldog's butler Tenny, and Reginald Denny as his hapless friend Algy, again providing the laughs in this action packed mystery.
